Precipitation variability, fertility, and metabolic stress over 5 millennia in the ancient Andes: A bioarchaeological path analysis.
Article in Science advances, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
Climate change is a pressing global issue. Research on living populations fails to capture the full range of possible responses. Archaeological and bioarchaeological research offers a window into how people adapted to past climatic changes. We investigate the relationship between human health and precipitation among archaeological populations in the Andes region of South America. We conduct a path analysis of precipitation, cribra orbitalia, and age-at-death to assess the evidence for metabolic responses to climate change. Our models suggest that cribra orbitalia was less common, and that fertility was higher, when precipitation was greater. Model results were characterized by uncertainty, emphasizing the high variety in human responses to environmental change.
